Reissued Oct. 26, 1920.

Ewen {02 citizen of the UnitedStates, residin UNITED STATES I T all whom it may concern:

Be it known that I, BART BILDERBAGK, a

at Bockville, in the county of Parke and tate of Indiana, have invented a certain new and useful Improvement in Metallic Smoke- 'houses, of which the following is a full,

clear, and exact description.

My invention relates to smoke-houses adapted to curing meat by the-use of a com- 'bination of heat, smoke and evaporation,

and the objects of the invention are; first, to provide a smoke-house which will efliciently distribute the heat and smokeevenly and to all parts of the meat treated therein second, to provide such a device whichwill afford proper collection and drainageof all liquids evaporated from the .meat; third, to provide such a device which will require a minimum fuel supply and produce a maxi mum curing power therefrom; fourth, toprovide such a device which will be indestructible and free of danger from fire or other similar action; and fifth, toprovide such a device which will be sightly, compact and economical .in construction and installation.

These objects I attain by {means of the device shown in thegaccompanying drawings, in which:

Figure 1, is a perspectiveview ofthe device.

Fig. 2, is a view of the device .withgthe front wall removed andshowing the internal construction thereof.

Similar letters of reference refer to similar parts throughout the several views.

The body, A, of the device consists of a housing or cabinet composed of four walls,

a top and a bottom,,as shown, all of which are constructed of substantial sheet metal.

The front wall of,the housing is provided with double doors, I) which tightly close the upper compartment, 0, and a furnace door, d, which is provided with a damper e, and which closes the lower compartment orfire box, 9.

The inner edge of the double doors, I), are flanged. or offset to overlap each other smoothly and are provided with a substantial two-bolt :lock, 7', which binds the two doors closely together and against the face of the cabinet, A.

Application 2, to a point slightly above the furnace 'door,,cl.

The inwardly curved ends of the inner Wall are fi nged' wnwardly, leaving an open space between the two, thus forming slot-like drain, '5, adapted to discharge all 'drippings conducted thereto by the curved side of the inner wall,

A metallic shield, m, in the form of an inverted trough, is suitably mounted above thedrain, 11, with only suiiicient vopenspace between the edge thereof and the corre sponding inner walls to permitthe drainage of drippings, and is adapted to prevent the passage of excessive heat and as ashes from the fire-box into the upper chamber. I

The inner walls, B, are properly spaced from the corresponding side walls to proand smoke is drawn by the draft from the smoke-pipe, =39, into .the upper portion of the cabinet; and the inner walls are provided with a multiplicity of openings forming perforations or vents, a, which admit heat and smoke in a spraylike manner to all parts of the upper chamber, C. I

A series .of metallic L-shaped cleats, 'r, is mounted upon the inner face of each inner wall, B, in pairs, for the purpose of supporting gratings, racks or other supports for meat while curing.

The oppositely disposed walls B with their converging lower portions, form an inner housing or container which serves to protect the meat being treated from direct contact with the fire, and to provide an even distribution of the heat and smoke from the fire to the contents of the inner housing.

The fire-box door, d, is suitably mounted upon substantial hinges, 7L, and is provided with a suitable catch, a.

upon the brick floor, 8, the smoke and heat from which passes upwardly through the flue-like spaces, 0, between the double side walls, and from there said smoke and heat is discharged in a spray-like manner through the many vents, 4.), directly upon all parts of the meat within the upper chamber, C. All moisture and other dripping from the curing meat falls upon the sloping inner walls, B, and is discharged by gravity through the slot-like drain, 11, immediately over the-fire, whereby all drippings are consumed or evaporated. A suitable flue-pipe, p, is provided in the top of the cabinet whereby proper draft and discharge of smoke and fumes is aiforded.

The advantages claimed for my smokehouse, over other devices used prior hereto for like purposes, consists; first, in the indestructible structure thereof; second, the compact and spacesaving formation; third, the perfect distribution of smoke and heat to all parts of the meat, whereby a more perfeet-and quicker curing of the meat is accomplished; and the economy attained in the reduction of fuel and time necessary to cure meat, as well as in the production costs of the smoke-house.

Having described my invention, I claim- 1. A smoke house comprising an outer housing and an inner housing occupying a portion of the interior of the outer housing,

said inner housing being adapted to contain a product to be cured, the top of the outer housing serving as a top closing member for the inner housing, the walls of the inner housing-being provided with openings for the purpose described.

2. A smoke house comprising an outer housing and an inner housing, there being spaces for the passage of smoke between the walls of the inner housing and the outer housing, the walls of the inner housing extending substantially to the front wall of the outer housing, said front wall being provided with an opening which communicates with the interior of the inner housing and a door for closing said opening, the walls of the inner housing being provided with openings for the purpose described.

3. A smoke house comprising an outer housing and an. inner housing, said inner housing being closed at the top thereof by the top wall of the outer houslng, the said walls of the inner housing being spaced from the side walls of the outer housing to provide spaces for the passage of smoke, the side walls of the inner housing extending substantiallyto the front wall of the outer housing, said front wall being provided with an opening and a door carried by the outer housing for closing said opening, the walls of the inner housing being provided "with openings for the purpose described.
